Nodes() function returns relationships?

问题

I am new to Neo4j. I have installed version 2.2.5 community edition to my machine. Downloaded sample data set cineasts_12k_movies_50k_actors_2.1.6. Followed the online training, all is good, except one query confused me a little.

match p = shortestPath( 
    (kevin {name:"Kevin Bacon"})-[*]-(keanu {name:"Keanu Reeves"}) 
) return nodes(p)

I was expecting that the returned values would only be the nodes. Reading the manual about nodes() it sounds like it should only return nodes. However I am getting both nodes and relationships in this case. Am I missing something here or is this a defect ?

回答1:

If you are seeing relationships in the Neo4j browser you can turn off "Auto-Complete" - look in the bottom right for the toggle. By default relationships between nodes returned in the browser are shown in the visual, even if not returned in the query.

Example
